Sybase to Oracle Data Conversion

Whats the quickest way to move data from Sybase to Oracle ? What options are available ?
Database objects (table ddls, procs, triggers - everything else is already in place in Oracle) - already provided by Vendor.
Overview about the database :
Datatype difference
Sybase datetime converted to Oracle Timestamp
Other datatypes are related
int - int
char - char
varchar - varchar
Timestamps are part of PK & FK in few tables.
Approx 1000 tables to convert
Some tables have 25- 75 million rows
Thank you
Yog

Another approach you might like to try is to use the manual approach of data migration.. where underlying idea is to bcp out the data from Sybase and thereafter use sqlloader to load data into the oracle tables.. and if you happen tro use DIRECT=TRUE with sqlloader nothing better.... its really fast..
sql developer would generate the bcp out script.. extract the scripts... run them on the sybase host ...move the dump files to oracle host... run the sqlloader scripts..
AT our end 15G worth data migration took 1 day using sql developer but the manual approach would do the stuff in 3-4 hours.
Anyway would like to put 1 issue I am facing..
In sybase the datetime contains the values to the level of Milisecond whereas when it comes to date column in Oracle it is just to the level of seconds .. => that if there is a primary key sybase table column.. and this truncation at orale level would make the inserts to fail with duplication errors... any thoughts on how to overcome this problem....
Thanks

Oracle date conversion

Hi all,
maybe anyone of you knows an answer to this:
Why does Oracle accept a date in format dd.mm.yyyy without explicitely converting to dd-mmm-yy in Windows but not in Solaris ? (It's the same program code producing exactly the same sql statement.)
Thank you
Marko

Hi Date format in Oracle is entirly depand on the NLS_DATE_FORMAT . You can see NLS parameter in V$NLS_PARAMETERS table of your database.. You can change for Your session using
ALTER SESSION
SET NLS_DATE_FORMAT ='dd/mm/yyyy'
But this is aplicable to your session only.. Please check this parameter in both Soraris as well NT ..

GL Data Conversion from Legacy to Oracle EBS

Hi All,
I am tasked with converting legacy data into GL. I have worked on other conversions like supplier, AR and AP conversions but never worked on GL conversion, so I don't know how and where to start, what are the pre-requisites for entering data into gl_interface table how to ensure that data is correct in the .csv file etc.
Kindly request you all to guide me in right direction. Hope to hear from you all very soon!!! :)
Regards

Hi,
When you talk about GL-Data it is the trial balance to be loaded from legacy to oracle applications.
You can use Web-ADI to upload it ,the check list are
The balance for each account comibnation in the legacy system to be mapped to GL-Oracle code combination balance
With respect to open AR, AP Invoices if the invoices are converted using a control account for migration in GL then
the the balance transfered from AP,AR need not be reversed in GL from the source receivables and payables.
In case if the same account combination are for migrating the balances from AP,AR to GL ..Then the balances transferred from AP,AR should be reversed ..so that it does not affect the TB-GL-Balance
Finally ensure that the balance for the TB-tallys with your legacy system and upload it using Web-ADI ,import and
review and post it.
Hope this points helps your GL-Data conversion.

Ramaa

RE: Oracle DATE data format conversion..

<C.M> Motta's question about dates and oracle>
Dealing with dates and Oracle is somewhat of a nuisance. Oracle is very
particular about how date strings are formatted, and if you get it wrong,
you get the (unhelpful) message that C.M. Motta showed us. However, if
you pass a DateTimeData to Oracle, Forte' does the right formatting for you.
If you do need to format the date prior to interacting with Oracle, use the
following format:
dd-mmm-yy <time component>
You can change the default format, but it is not easy.
If you customise Express generated code that interacts with an Oracle
database, again, make sure that you pass a DateTimeData, and not the
.TextValue.
Good luck!

Cheers:
Most likely what is happening is that you are using the default date
format of Oracle, and you are sending a four-character year. As follows:
SQL> insert into jimbo values ('01-dec-1997')
2 /
insert into jimbo values ('01-dec-1997')
ERROR at line 1:
ORA-01830: date format picture ends before converting entire inputstring
>
Oracle defaults to a format of 'dd-MON-yy'
You can either truncate the year, or manipulate the date to match the standard
database as follows:
insert into jimbo values (to_Date('01-jan-1997', 'DD-MON-YYYY'))
\jimbo

Issue with Date Conversion when loading XML File into Oracle 10g Database

Hello all,
I have the interface shown in the screenshot below. In it, amongst other actions, I'm mapping an XML file element representing a date to an Oracle table column defined as DATE. The source and target columns are highlighted in the screenshot.
!http://img223.imageshack.us/img223/1565/odiscr275.jpg!
When I execute the interface, I get the following error message:
java.lang.IllegalArgumentException at java.sql.Date.valueOf(Date.java:103)
I'm assuming this refers to the date conversion!
I've already tried replacing SRC_TRADES.DEAL_DATE with TO_DATE( SRC_TRADES.DEAL_DATE, 'DD/MM/YYYY' ) in the Implementation tab. This function was not recognised when I executed the interface, so it didn't work! The date value in the XML file is in DD/MM/YYYY format.
I'm guessing that Oracle SQL Date functions don't work in the Implementation tab. Please could somebody let me know:
1. Which Date Conversion function I could use instead?
2. Where I can find a reference for the methods/functions I can use in the Implementation tab (if such a reference exists)?
Cheers.
James

Hi.
Try to change the execution area to staging area. After You change it, write in the mapping box just SRC_TRADERS.DEAL_DATE. When You use TO_DATE, the source field typu should be varchar2, not date (as it is in your source datastore)

Date datatype in Sybase to Oracle

We are in the process of migrating Sybase Adaptive Server 12.5.2 to Oracle 10g. However, we came across a "Date" datatype in Sybase and am not able to map it to corresponding Oracle 'Date" datatype.
In OMWB, Tools -> Options-> DataType Mappings, I am not able to see the "Date" in source data types.
Any insights please.
Diwakar

Diwakar,
I have filed a bug 4579859 on this issue.
This is not a trivial problem with the datatype options, a table with the date datatype will fail to map.
Do you have many tables with this datatype, is it practical to convert these tables to datatypes recognised by the workbench (such as datatime or even varchar)?

Sybase ASE to Oracle 11g conversion

Hi,
Can anyone please look at the following Sybase ASE to Oracle 11g conversion - the top remarked code is the original Sybase version and the two UPDATE blocks below are hopefully doing the same task... What I need to know is if there is a more simple (less code change) way of doing the same task, either as a single UPDATE or preferably even more similar to the original Sybase code..?
-- /* now apply allocations */
-- update diary_items
-- set id_user = ia.id_user ,
-- tx_icon_user = 'urlcats:/user_grey.gif?method:getAllocationInfo'
-- from diary_items di,
-- item_allocation ia
-- where di.id_diary_item = ia.id_object
-- and ia.id_object_type = 'W'
-- and ia.id_user != 'autocats'
-- OK!
-- ??? Need to check if second UPDATE which is the same as above is required again...
/* now apply notes */
UPDATE diary_items
SET diary_items.tx_icon_user =
( SELECT 'urlcats:/user_grey.gif?method:getAllocationInfo'
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item )
WHERE EXISTS
( SELECT item_allocation.id_object
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item
AND item_allocation.id_object_type = 'W'
AND item_allocation.id_user != 'autocats' )
UPDATE diary_items
SET diary_items.id_user =
( SELECT item_allocation.id_user
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item )
WHERE EXISTS
( SELECT item_allocation.id_object
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item
AND item_allocation.id_object_type = 'W'
AND item_allocation.id_user != 'autocats' )
Many thanks!!!

I managed to work it out in the end - here's the solution...
/* now apply allocations */
update diary_items
set ( id_user,
tx_icon_user ) =
( select ia.id_user,
'urlcats:/user_grey.gif?method:getAllocationInfo'
from diary_items di,
item_allocation ia
where di.id_diary_item = ia.id_object
and ia.id_object_type = 'W'
and ia.id_user != 'autocats'
)

Transporting data between sybase and oracle

I want to know how do you transport data from sybase to oracle. The table are created in sybase and we want to move
everything over to Oracle8i

I want to know how do you transport data from sybase to oracle. The table are created in sybase and we want to move
everything over to Oracle8i .if sysbase has a facility to export the tables as comma separated text files, export them and then user sql *loader to load the data into oracle.
you can check out oracle utilities documentation for sql *loader case studies.
if there is a huge amount of data, you can try oracle trasnparent gateway for sybase. thank you..:>)

DATE format problem, migrating from Sybase to Oracle 9i

Hi,
We are in a process of migrating the database from Sybase to Oracle 9i, everything going fine except the data load of couple of tables.
The workbench created the control file, data & related files to load the data into Oracle using the SQL*LOADER.
But coule of data files having HH:MI:SS:xxx AM in the DATE field, which Oracle is failing while laoding the workbeck created the destination table with the column data type = DATE, so how to insert the milliseconds along the date like Mar 25 2004 12:00:00:000 AM
Thanks

In your control file for SQL*Loader, specify the timestamp with format like "Mon DD yyy hh:mi:ss:ff3AM".

SQL Server Date Conversion to Oracle Date

I am new to ODI and am trying to figured out how to move a SQL Server date datatype value to an Oracle date.
Thanks in advance.

SQLServer datetime datatype is moved to an Oracle TIMESTAMP datatype via the technology's data type mapping. That particular LKM 'SQL to SQL' is written in java so reads from SQLServer into java datatypes then writes back out to Oracle.
Cheers

Experiences migrating from Sybase to Oracle

Hi all,
I have been asked to look into migrating a database from Sybase to Oracle.
I know there is lots of info on Oracle's website, which I have downloaded, but I was just hoping for some info about some of your experiences regarding your processes. What are the gotchas. I suspect there will be a few.
Anything that will help would be of interest.
Many thanks
VicC

HI VicC,
I work within the SQL Developer team and not a customer as such, but the follow maybe of use.
SQL Developer is a migration aid, its not 100% magic bullet.
SQL Developer does alot of the manual conversion for you quickly. But you may find Testing / Tuning and the application migration (if any) take you the most amount of time.
SQL Developer aims to migrate you tables, indexes, and data without issue. But SQL Objects like Procedures, Triggers, Views and Functions conversion will likely require manual work on top of the automatic conversion provided by SQL Developer.
SQL Developer does not yet automatically handle things like the tablespaces structure or the the logins. Although these things can be scripted and managed more easily within SQL Developer.
I would recommend downloading and performing the migration from a non production instance ASAP.
SQL Developer can perform a migration quickly and you will then be able to assess what SQL Developer can and cant do for you.
I would recommend creating a migration repository on an Oracle database local (install Oracle XE if you dont have a local database) to the SQL Developer instance you are using.
I would also recommend downloading SQL Developer 2.1
Here are some key sites regarding Sybase migrations.
http://www.oracle.com/technology/tech/migration/workbench/viewlets/sqlserver.html . This viewlet for SQL Server is the same process for Sybase.
http://www.oracle.com/technology/obe/hol08/sqldev_migration/sybase/migrate_sybase_otn.htm . This Oracle By Example takes you step by step through a Sybase migration including some gotchas
http://dermotoneill.blogspot.com/2008/06/sql-developer-migration-workbench-151_11.html . This is my blog outlining the steps to perform a Sybase migration.
